Node.js, Python, and Ruby are single-threaded. They all have ways to achieve concurrency and multi-process usage right now, and so does OCaml. I get it, people really want OCaml multicore–and it's coming–but that by itself is not stopping OCaml from being an industrial-strength, production-ready language right now.

For generations, the only way to use multiple CPUs was multiple process and asynchronous syscalls. So for C it was ok, but for OCaml a reason not to use the language.
